CRS Version

The version of CRS can be higher than the version of database/ASM software. The commands to see the same are

crsctl query crs softwareversion
crsctl query crs activeversion

So although the difference between the two commands might be obvious I am not sure if this is documented anywhere. Also after upgrading from 10.2.0.1 to 10.2.0.2/10.2.0.3 the active version does not seem to change. This maybe due to bug 5278777 which should be fixed in the 10.2.0.4 patchset.

I upgraded a couple of clusters yesterday from 10.2.0.1 to 10.2.0.3 (without any issues per se) and this is what I see after the CRS upgrade.

Also a rolling upgrade of CRS causes the VIP to relocate to some other node and you have to manually relocate the same using crs_relocate. This is mentioned in the patchset readme though I am not sure how many customers actually read the section “Known Issues”.
